To all whom it may concern:

Be it known that I, Ranrn G. TAYLOR, a citizen of the United States,residing at Davenport, in the county of Scott and State of the car orthe other, is that one is right and the other left, a brief descriptionof one will suffice.

Each hopper has a long sloping bottom 5 Io a, have invented new anduseful lm-' portion, a, that inclines toward the center 0 provements inOperating Mechanism for of the car, the lower edge of which termi-Car-Doors, of which the following is a full, nates in a suitable planemediate the under clear, and exact description. side of the center-silland the rails, and has -My invention relates to mechanism for shortsloping portions 6, that incline in 10 closing and controlling thedischarge openopposite directions from the center of length 65 ing ofthe hoppers of dump-cars, and partoward the ends of the car, whoselower. ticularly, of the convertible liat-bottomed edges terminateabout. midway the height of 'freight car and dump-car described in thethe center-sill.

To accomplishthe coupling between the connecting rod and this, I provide the doors G,(l, of each pair cross-beam. of hoppers with a bracket 42, consisting,

Bettcndort, deceased, hcreinbcfore of each door with the shorter leguppermost, referred to, the car is shown to possess two its mostadvanced portion will be almost corresponding alining and opposedhoppers vertical. An I-beam H, of suitable length on each side of thecenter-sill, that are arhas its ends riveted or otherwise secured to rranged asto discharge toward the center this advanced portion of thebracket, and of the car below the plane of. the ccnter-sill.transversely passin under the center-sill Two of these hoppers are inthe same-transconnects one door with the other door of the verse planes,and as the only difference in the pair. Immediately under the centersill construction between this pair, whether 10- this I-beam is clampedbetween the attachcat/ed on one side of the center of length of 110 holdthe doors in any position desired, without the necessity of ratchets orbrakes, and which can operate two doors at once. This, I accomplish bythe means hereinafter fully described, and as particularly pointed outin the claims.

In the drawings: Figure 1 is a side elevation of a portion of a dump-carembodying my improvements. Fig. 2 is a vertical lonand b, rivetedthereto. The portion of the edges of the side-walls between the loweredges of the long and short inclined edges of the hopper are straightapd complete the discharge-opening of said hopper. The

edges of this discharge-opening are suitabl reinforced and it is closedby a door (Jr, which preferably, consists of a single plate of sheetmetal sbaped so as to close said ing plates f, f, of a. coupling; eachof said 1 :uoaaeeov (a neye extending-there-throug the plane of the webof said I-beam' The screw-threaded ends of a V-shaped yoke or 5 clevis Jare extended through the eyes of said. coupling lugs, and secured to thelatter by means of nuts I, it. Now, the doors-G are kept closed orpartially :or wholly opened, according as desired, by meansof '20suitable stud ='projecting down from a supporting-plate n secured to theunderside of the center-sill. The connecting-rod, M, has an eye at oneend that links with clevis J, and is Bifurcated at its other end toenable it to pass both above and below the Wormgear. These bifurcations,0, 0, have their ends crooked slightly and pivotally connected to acrank-pin, Q, that is secured in and projects on both sides from thewormgea Now, the worm gear, the connectingrod and the doors are soassembledwith relati'on to one another that when the worm gear is turnedthrough the medium of the worm and worm-shaft, the 'door will be pned orclosed and held in any position desired without the necessity of a pawl-and ratchet. The friction between the worm and Worm gear is in itselfsufiicient to prevent any lost movement. At the same time, 40 theleverage that can be exerted by the Worm and worm gear; is such that oneman can have perfect control of the doors.

What I claim and desire to secure by Let ters Patent is:

4a 1. A dump-car, comprising a hopper depending below the plane of theunderframe and having a discharge-opening therein, a door for closingsaid discharge-opening, a I worm, the axis of which is arranged trans-5C aersely of the car, a horizontally disposed worm-gear' actuatedthereby, a connecting- ,rod, pivotally connected to said gearat oneend,'and means connecting it to the door at the other end. I

2. A dump-car, comprising a hopper d'epending below theplane of'theunderframe and having a diScharge-opening, therein, a dgor for closingsaid discharge-opening, a

A dump-car, comprising twohbppers arranged one on: each sideof the center Width of the car, anddependingl belowfltheavin dies charge-openings therein, a door for cusing;

plane of the underframe, and

the said opening of each hoppena trans verse-men'iber' connectingsaiddoors, a worm,

whose axis is transverse of. the car, a horizontally disposed worm-gearactuated by said worm, a connecting-rod disposed between said hoppersand pivotallyconnected to said worm-gear at one end, and adapted toimpart the motion: of the same. to-said transverse member. v a

5. A dump-car comprising'two hoppers arranged one on each side of thecenter of Width of the car, and depending below the plane of theunderframe, and havin discharge-openings therein, a door. for c osingthe said opening of each hopper, a transverse member connecting vsaiddoors, a. worm whose axis is transverse of'th e car, a horizontallydisposed wo'r.- said worm, a connecting-rod disposed between saidhoppers, and pivotally connected .to said worm-gear at one end, and ayoke connecting theopposite end of said connecting rod to saidtransverse member.

' 6, A dump-car comprising two hoppers arranged ig ne on each side ofthe center of width of the car, and depending below "the plane of theunderframe and having discharge-openings therein, a door for closingthesaid opening of each hopper, an I-beam con ice-ting said doors, a Worm,whose axis is transverse of the car, a horizontally disposed worm-gcaractuated by said worm, a connecting-rod disposed between said hop persand pivotally connected to said wormgear at one end, and a couplingclamped to said I-beam between said hoppers, and a, yoke or clevisconnecting-said connecting-rod to said coupling.

i 7. A dump-car comprising two hoppers arranged one on each side of thecenter of Width of the car, and depending below the plahe of theunder-frame and having discharge-openings therein, a door for closingthe said opening of each hopper, an I-beam gear actuated by IOU gear atone end, and a coupling consisting of two plates clamped to the web ofsaid I-beam mediate said hoppers, and having lugs projecting therefrom,and a yoke, the ends of which eatend through and are sccured inperforations in said lug, and which connects said connecting rod andcoupling.

8. A dump-car comprising two hoppers arranged one on each side of thecenter of width of the car alongside of each other that depend below,and have discharge-openings below the plane of the under-frame of thecar, a hanging door for each of said discharge openings, a bracketsecured to and projecting from each of said doors, a trans verse I-beamhaving its ends secured to said brackets, a transversely arranged worm,a horizontally disposed Worm-gear actuated thereby, and a connecting-rodfor imparting motion from said worm-gear to said I-beams and doors.

9. A dump-car comprising two hoppers arranged one on each side of thecenter of width of the car alongside of each other that depend below,and have discharge-openings below the plane of the underframe of thecar, a hanging door for each of said discharge-openings, a bracketsecured to and projecting from each of said doors, a transverse I-beamhaving its ends secured to said brackets, a transversely arranged worm,a horizontally disposed worm-gear actuated thereby, a coupling securedto said I-beam mediate said hoppers, a yoke, or clcvis, the ends ofwhich are secured to coupling, and connecting-rod connecting saidworm-gear and yoke.

In witness whereof I have hereunto set my hand this 18th day of October,1910.
